Tire tread



FIG. 1 is a perspective view of a tire tread showing my new design, it being understood that the pattern is repeated uniformly throughout the circumference of the tread;

FIG. 2 is a front elevational view thereof; the rear elevation, top, and bottom plan views being a mirror image thereof;

FIG. 3 is a left side view thereof; the right side being a mirror image thereof; and,

FIG. 4 is an enlarged fragmentary view from upper 4-4 to lower 4-4 in FIG. 2.

The broken lines defining the side wall, inner bead and the peripheral boundary between the tire tread and sidewall illustrate environmental subject matter only and forms no part of the claimed design.
